Magnetic motor

Abstract

A magnetic motor is obtained which is free from pass-through current, and which can achieve high output torque, stable rotation and high efficiency. The motor comprises rotors 4, 5 having permanent magnets 12 and rotatably disposed around a rotating axis, a magnetic sensor 25 disposed at a periphery of the rotors and a plurality of electro-magnetic coils 10, and control means which controls electric current to the electro-magnetic coils 10 based on detection of magnetism from the permanent magnets 12 by means of the magnetic sensor 25. The rotor is equidistantly divided in a circumferential direction into a plurality of regions, the number of which is the same as that of the electro-magnetic coils 10. Each region comprises a portion wherein a plurality of permanent magnets 12 are disposed in a circumferential direction and a portion wherein no permanent magnets 12 are disposed. Each permanent magnet is disposed inclined against a radial line extending outwardly from the rotating axis. The current supply control means 30 switches the direction of the electric current to the electromagnetic coils based on the signal from the magnetic sensor and supplies electric current after a lapse of predetermined time from the detection of magnetism by means of the magnetic sensor.
